For every polynomial function (such as quadratic functions for example), the domain is all real numbers. if the parabola is opening upwards, i.e. a > 0 , the range is y ≥ k ; if the parabola is opening downwards, i.e. a < 0 , the range is y ≤ k .

Answer is 28 units because it’s 15 over 42 is equal to 10 over “x”, then you cross multiple which you end up with 15x=420 divide 420 from 15 which equals 28.

. A rectangular garden will be divided into two plots by fencing it on the diagonal. The diagonal distance from one corner of th

ASHA 777 [7]

Answer:

Step-by-step explanation:

The width = x

The length of the garden is three times the width => the length = 3x

The diagonal distance is five yards longer than the width=> the width=x+5

pythagorean theorem:

$(x+5)^{2} = 3x^{2} +x^{2} \\=> x +5 = \sqrt{( 3x)^{2} +x^{2}} \\=> x+5= \sqrt{10x^{2} } \\=>x+5= \sqrt{10} x\\=> \sqrt{10} x - x=5\\=> x= \frac{5+5\sqrt{10} }{9} (yd)\\\\ the diagonal = x+5 = \frac{5+5\sqrt{10} }{9} +5= \frac{50+5\sqrt{10} }{9} (yd)$

My English is not too good but I hope you will understand.
